What helps an earthworm dig through the soil and where is this located?
An earthworm's ability to dig through soil is aided by its strong, muscular body and the hydraulic pressure created by its body fluids. The earthworm's setae, tiny bristle-like structures on its body, also help it grip onto soil particles as it moves. These structures are located along the earthworm's body segments.

What type of reproduction does annelid use?
It is thought that annelids were originally animals with two separate sexes, which released ova and sperm into the water via their nephridia.[3] The fertilized eggs develop into trochophore larvae, which live as plankton.[33] Later they sink to the sea-floor and metamorphose into miniature adults: the part of the trochophore between the apical tuft and the prototroch becomes the prostomium (head); a small area round the trochophore's anus becomes the pygidium (tail-piece); a narrow band immediately in front of that becomes the growth zone that produces new segments; and the rest of the trochophore becomes the peristomium (the segment that contains the mouth).[3]

What is the purpose of the prostomium?

What is the function of the prostomium?
Prostomium (sometimes also called acron) is the first body segment in annelids worms. It is in front of (but does not include) the mouth, being usually a small shelf- or lip-like extension over the dorsal side of the mouth. It sometimes bears antennae and eyes. By feeding, it often functions like a kind of overlip. The shape and composition of prostomium are important for annelid systematics.http://en.wikipedia.org/wiki/Prostomium

The number of segments between prostomiun and clitellum?

What is the Different between the prostomium and peristomium in polychaetes?
